Mathematical and theoretical biology

Mathematical and theoretical biology uses math and theories to understand how animals, plants, and microscopic life like germs act in nature. It helps us to better understand how living things interact by looking at their behaviors, how they change, and how they could potentially be affected by their environment. For example, mathematical and theoretical biology may be used to study how the number of birds in an area can impact the number of insects. This type of research helps us to better understand and protect living things by predicting the kind of impacts we may have on them.
